A resident of a long-term care facility receives 12.5 mg metoprolol (Lopressor) at 8 AM and 8 PM daily. Before administering this drug, the nurse should perform and document what assessment findings?
Temperature and respiratory rate
Heart rate and blood pressure
Level of consciousness and pain level
Oxygen saturation and respiratory rate
The Correct Answer is B
A) Temperature and respiratory rate:
While monitoring temperature and respiratory rate are important aspects of a comprehensive assessment, they are not the priority assessments before administering metoprolol. Metoprolol is a beta-blocker primarily used to lower heart rate and blood pressure, so assessing the client's heart rate and blood pressure is more relevant.
B) Heart rate and blood pressure:
This is the correct answer. Before administering metoprolol, it is essential to assess the client's heart rate and blood pressure. Metoprolol is a beta-blocker medication that primarily affects heart rate and blood pressure. Monitoring these vital signs helps ensure that the medication is administered safely and effectively.
C) Level of consciousness and pain level:
Assessing the client's level of consciousness and pain level are important aspects of nursing care, but they are not the priority assessments before administering metoprolol. These assessments may be relevant depending on the client's overall condition and specific care needs, but they are not directly related to the action or side effects of metoprolol.
D) Oxygen saturation and respiratory rate:
Monitoring oxygen saturation and respiratory rate are important aspects of respiratory assessment, but they are not the priority assessments before administering metoprolol. While metoprolol can affect respiratory function as a potential side effect, its primary action is on heart rate and blood pressure. Therefore, assessing heart rate and blood pressure are more pertinent before administering this medication.

Correct Answer is A
Explanation
A) The sympathetic nervous system is responsible for "fight or flight":
This is the correct answer. The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body to react to perceived threats or stressors by increasing heart rate, dilating pupils, redistributing blood flow, and releasing stress hormones such as adrenaline and noradrenaline.
B) The sympathetic nervous system helps us to rest and digest:
This statement is incorrect. The parasympathetic nervous system is responsible for the "rest and digest" response, which promotes relaxation, digestion, and conservation of energy.
C) The sympathetic nervous system includes the cranial nerves:
This statement is incorrect. The sympathetic nervous system is primarily associated with the thoracolumbar region of the spinal cord and does not include the cranial nerves, which are primarily associated with the parasympathetic nervous system.
D) The sympathetic nervous system can lower blood pressure:
This statement is incorrect. The sympathetic nervous system typically increases blood pressure as part of the "fight or flight" response by increasing heart rate and constricting blood vessels to redirect blood flow to vital organs and muscles.
Correct Answer is ["100"]
Explanation
We are given the following information:
Medication: Ticarcillin/clavulanate 3.1 g
Administration route: Intermittent IV bolus over 30 minutes
Available solution: Ticarcillin/clavulanate 3.1 g in 50 mL 0.9% sodium chloride (NSS)
However, the IV pump controls the rate of delivery over time (usually in hours). An intermittent bolus means the medication is infused all at once over a shorter period (30 minutes in this case).
The pump rate calculation here focuses on the total volume of the available solution containing the medication to be delivered, not necessarily on the medication amount itself.
Therefore, we need to find the rate at which the total volume of 50 mL solution should be delivered over 30 minutes.
Conversion is necessary because pump rates are typically set in hours (hr).
Time (hours) = 30 minutes / 60 minutes/hour = 0.5 hours
Now, calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)
Flow rate (mL/hr) = 50 mL / 0.5 hours = 100 mL/hr
Round to the nearest whole number as requested.
Therefore, the nurse should set the pump to deliver approximately 100 mL/hr. This ensures the total 50 mL solution containing the 3.1 g of ticarcillin/clavulanate is delivered over the intended 30-minute period.
